标准摘要
[中文适用范围]: IEC 60502的本部分规定了额定电压3,6/6(7,2)kV至18/30(36)kV电力电缆附件型式试验的试验要求,符合IEC 60502-2。不包括用于特殊应用的附件,例如架空电缆、海底或船舶电缆或危险情况(爆炸性环境、耐火电缆或地震条件)。一旦成功完成,就没有必要重复这些测试,除非材料、设计或制造工艺发生了可能影响性能特征的变化。测试方法包含在 IEC 61442 中。 注:本标准不会使基于国家标准和规范和/或令人满意的服务性能证明而获得的现有产品认证无效。然而,根据此类国家标准或规范批准的产品不能直接声称对该IEC标准的批准。根据供应商和买方和/或相关合格评定机构之间的协议,可以证明对早期标准的符合性可以用来声明对本标准的符合性,前提是对任何附加型式测试进行了评估这可能需要进行。作为测试序列一部分的任何此类附加测试都不能单独进行。 [外文原描述]: IEC 60502-4:2010 specifies the test requirements for type testing of accessories for power cables with rated voltages from 3,6/6 (7,2) kV up to 18/30 (36) kV, complying with IEC 60502-2. Accessories for special applications, such as aerial cables, submarine or ship cables or hazardous situations (explosive environments, fire-resistant cables or seismic conditions), are not included. It is not necessary to repeat these tests, once successfully completed, unless changes are made in the materials, design or manufacturing process which might affect the performance characteristics. Test methods are included in IEC 61442. Significant technical changes with respect to the previous edition are as follows: a) the range of approval has been revised; b) a water immersion test requirement for outdoor terminations has been introduced; c) examination of accessories at the end of the test sequence is to be recorded in a test report for information only; d) both the a.c. and d.c. test are to be carried out; e) the heating cycle test has been added to Table 11.
